I think the artist needs help if they animate a school-shooting like this.
It's certainly not something to be admired in any form or way. There was that johnny phantom brony who did dumb shit like this, up to the point where he packed two weapons and ammo and went on a killing spree, killing three people and then himself. What a dumbass.
Ok this is pretty disgusting, but when the girl with the gun shot the other already dying girl on the floor in the fucking head. Yea, this guy is pretty fucked up.
